The Claim
In lean, normotensive young adults, 48 hours of glucose-induced hyperinsulinemia reduces insulin sensitivity by approximately 35% as measured by the homeostasis model assessment, and this reduction is significantly correlated with the decline in nocturnal heart rate variability.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In healthy young adults, maintaining high insulin levels for 48 hours through glucose infusion lowers insulin sensitivity by about 35% and is associated with a measurable decrease in nocturnal heart rate variability.

Excess insulin from prolonged sugar intake signals the brain to reduce the nerve activity that slows the heart at night, which also makes the body less able to respond to insulin, causing both the heart rate to stay high during sleep and blood sugar control to worsen.
What the research says
1 studyWhen healthy young adults were given extra sugar for two days, their bodies became less responsive to insulin, and their heart’s ability to slow down at night also got worse — and these two changes happened together.
